Molecular current modulator consisting of conjugated polymer chain with chemically attached photoactive side groups

A scheme for an optically controlled current modulator is put forward, base d on properties of a conducting polymer containing photochromic moieties ch emically attached to the main chain. The idea is supported with results of calculations of local states for charge carriers formed in the vicinity of dipolar species in molecular materials, and with measurements of the drift mobilities in polysilane copolymers containing polar benzaldehyde 2,4-dinit rophenylhydrazone groups.
